| Abstract | Iron is known to cause deleterious oxidative reactions in muscle food. The concentration of the two iron forms, heme and nonheme, varies in beef skeletal muscles of different physiological origin. We evaluated beef Longissimus dorsi (LD) and Psoas major (PM) muscles heme and nonheme iron concentrations to correlate those to fresh meat retail display color properties, discoloration, and lipid oxidation during a simulated retail display and storage. Iron forms concentrations were correlated with beef quality indicators such as instrumental color characteristics and lipid oxidation over a period of 9 days retail display and storage. Results indicated that concentrations of both the heme and nonheme iron were significantly lower (p < 0.05) on day 9 as compared to day 1. Heme iron concentration correlated moderately with redness (r = 0.72 and 0.44) and it correlated weakly with discoloration (r = −0.34 and −0.47) in LD and PM samples respectively. Nonheme iron concentration correlated weakly with redness (r = 0.31 and −0.02) and discoloration (r = 0.38 and 0.13) in the LD and PM respectively. The Lipid oxidation of both the LD and PM muscles increased (p < 0.05) with increase in retail display and storage time. However, lipid oxidation was noticeably higher in the PM muscle than the LD. The findings suggest that concentration of iron forms were not a strong predictor of time dependent color and quality changes in beef muscles. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
